Planar Head - Light study tool

Drawing portraits becomes much easier when you can clearly see how light and shadow fall on the head. This app is a simple visual reference that helps artists study lighting while drawing portraits and heads.

You can rotate the head freely to match the angle of your drawing, then move the light around to see how shadows change. Adjust the light direction and intensity to explore soft lighting, strong contrast, or more dramatic setups. This makes it easier to understand where shadows should fall and how form is affected by light.

The app is designed to be quick and distraction-free. Use it alongside your sketchbook or tablet while drawing. It works well for quick practice studies, lighting experiments, or as a reference while finishing a portrait.

Useful for artists at any level, this tool helps you draw heads with more confident lighting, clearer shadow placement, and stronger sense of form...without guessing.
